changing old shower handle trim

I am updating a bathroom from the 70s. I have changed the showerhead to a hand-helf variety, but also want to change the trim on the handle. I bought something that looked like it would work, but it does not. The original trim was a 7" diameter Moen with a knob with "crystal" center. The screwholes are 1 1/8" apart. (The Danko that I bought has wider screwholes.)

I'm switching everything to oil rubbed bronze (anything close would be fine), so that complicates it a bit. I hope I do not need to change the valve itself.

I'm planning to buy a Tasagi Japanese style tub that is designed to fit into the kind of shower stall I have, so it would be even better if I could figure out a way to lower the handle so I could reach it while seated in from the tub, but I'll settle for keeping it where it is and just getting it to match.

There is NO "generic" shower valve trim. ( But there are aftermarket, brand specific items available.). You MUST get trim made for your EXACT brand AND model.

Now, Moen is one of the most widely found brands. You must specify if yours is a pull-out type or just a turn-type. Moen themselves, and many aftermarket companies make trim for your valve, including in the bronze. Take your parts to a good plumbing supply and they will have what you need,
